초록 ▼

A battery system includes a battery assembly having a plurality of modules, which are controlled by a system control circuit, each module including a module control circuit and a module by-pass circuit which is controlled via the module control circuit so as to suppress the charging variation among the plurality of modules. Each control circuit and the system-controlling circuit are connected to each other via a bilateral transmission medium and each module by-pass circuit is controlled based on information bilaterally transmitted between each module control circuit and the system control circuit via the bilateral transmission medium.

대표청구항 ▼

[ What is claimed is:] [1.]1. A battery system, including a battery assembly that includes a plurality of modules, each of which includes a plurality of battery cells serially connected to each other for driving electrical loads by performing charging and discharging operations, and which is controlled by a system-controlling unit;wherein each module includes measuring means for measuring voltage of each module, a module-controlling unit for transmitting a value of said measured voltage of said module to said system-controlling unit and for receiving a reference voltage value which is set in said system-controlling unit, and a module by-pass device connected to each module in parallel, which is situated for by-passing a part of the charging current for said module, and module-by-passing device-drive means for driving said module by-pass device based on a result of comparison between said measured voltage of said module and said reference voltage value; andwherein each battery cell includes a battery cell by-passing device connected to each battery cell in each module in parallel, which is situated for by-passing a part of the charging current for said battery cell, and battery cell by-passing device-drive means for turning on said battery cell by-passing device based on a variation in voltage values among battery cells in said module.
